1.4.3 ORIGINAL TRAILING EDGE SENSOR

During one-to-one copying, copy paper is fed to the registration roller in advance
(while the original is still being scanned), to increase the copy speed. The trailing
edge sensor monitors the stack of originals in the feeder, and detects when the
trailing edge of the last page has been fed in. The main CPU then stops the copier
from feeding an unwanted extra sheet of copy paper.
